parabolic orbit

In this paper we did research on the heat flow, temperature, structural changes, and their influencing factors of parabolic satellite antenna in near-earth orbit, which provides future theoretical references for antenna thermal and structural design.

本文以抛物面型星载天线为研究对象，分析其在近地轨运行时的外热流、温度场和结构场的变化情况和影响因素，为天线的热设计和结构设计提供理论依据。
